<Operation handle recess shape>
In FIG. 1, FIG. 3, and FIG. 4, the portion adjacent to the operation handle 30 of the lid peripheral dividing surface 23 is an operation recess 33 that is recessed toward the back side, and the operation recess 33 extends to the vicinity of the insertion port 8. Has been stretched.

  Details of the configuration of the operation handle 30 and the operation recess 33 will be described with reference to FIGS. 6 and 7. 6 and 7 are cross-sectional views taken along the line B-B in FIG. 1, and illustrate a cross-sectional configuration of the operation handle 30 portion when the lid body 7 is closed.

  FIG. 6 shows a state in which a finger is inserted into the operation recess 33 to open the lid 7 by operating the operation handle 30 to the back surface side of the operation handle 30, that is, downward in the drawing.

<Cover operation handle>
Next, as shown in FIG. 7, the operation handle 30 is moved forward by pulling the operation handle 30 forward, and the obtuse angle hook 29a is moved from the closed position to the open position in conjunction with the operation handle 30 as described later. It moves away from the hook receiving means 37a and changes from the “closed state” to the “handle operating state”, and the lid 7 can be opened.

  Next, the configuration and operation of the locking hooks 29a and 29b interlocked with the operation of the operation handle 30 described in FIGS. 6 and 7 will be described with reference to FIGS. FIGS. 8 and 9 are partial perspective views showing a part of the structure of the lid body 7, and are enlarged views of a portion K in FIG. 4 (A), with the operation handle 30 being removed with the first lid frame 35 removed. Details of the configuration of the locking hooks 29a and 29b are shown.

  10 to 12 are cross-sectional views in the EE direction of FIGS. 8 to 9 and show cross-sectional views at the same place as the EE cross-section of FIG.

  As shown in FIG. 4A, the operation handle 30 is part of a ring shape that is substantially concentric with the outer periphery of the lid body 7 and is provided along the back side of the lid body 7 and the outside of the cylindrical side surface. The first support shaft 39 is pivotably supported.

  The radial cross-sectional shape is shown in FIGS. The locking hooks 29a and 29b are on the opposite side of the lid body 7 with respect to the lid fulcrum means 24, and are lids orthogonal to the rotation axis constituted by the hinge pin 26 or the pin receiving hole 27 which is the rotation axis of the lid fulcrum means 24. It is provided in a plane including the maximum diameter portion of the body 7.

  One end of the operation handle 30 is extended toward the obtuse angle hook 29a so as to form a locking hook operation portion 40.

  The obtuse angle hook 29a is located between the “closed state” where the obtuse angle hook 29a is in the closed position with respect to the first lid frame 35 and the open position in the “handle operation state” when the operation handle 30 is operated. Is pivotally supported around a support shaft 41 of the shaft. The second support shaft 41 is provided with a torsion spring 42a coaxially, and the obtuse angle hook 29a and the hook receiving means 37a provided in the locking hook control means 38 are engaged to lock the lid 7 in the closed position. Energized in the direction. When the operation handle 30 is operated from the “closed state” by the locking hook operating portion 40 acting on the receiving portion 43 obtained by extending a part of the obtuse angle hook 29a, the obtuse angle hook 29a is set to the “handle operation state”. be able to.

<Acute angle hook>
Next, the configuration of the acute angle hook 29b will be described with reference to FIGS. The acute angle hook 29b is adjacent to the obtuse angle hook 29a, is provided on the opposite side of the operation handle 30 with respect to the obtuse angle hook 29a, and is pivotally supported around the second support shaft 41. The second support shaft 41 is provided with a torsion spring 42b coaxially, and biases in a direction to open the acute angle hook 29b, that is, in a direction away from the hook receiving means 37b provided in the locking hook control means 38. .

  8 and 10 show a “closed state” in which the obtuse angle hook 29a is in the closed position and engages with the hook receiving means 37a to close the lid body 7 as in FIG. 5A. At this time, the acute angle hook 29b is in the open position.

<Cover opening / releasing operation>
When the lid 7 is opened from the “closed state” when the clothes 6 are put in and out, the operation handle 30 is operated as shown in FIGS.

  9 and 11 show a state in which the operation handle 30 is operated as in FIG. 7 and the locking hook operation portion 40 provided at one end of the operation handle 30 acts.

  As shown in FIGS. 9 and 11, the locking hook operating portion 40 pushes the receiving portion 43, which is one end of the obtuse angle hook 29 a, to rotate the obtuse angle hook 29 a in the direction of the arrow, that is, in the opening direction. " Further, when the operation handle 30 is pulled toward the front side, the engagement between the obtuse angle hook 29a and the hook receiving means 37a remains released, so that the lid 7 can be opened toward the front as shown in FIG.

<Cover closed state>
When the lid 7 is closed, the obtuse angle hook 29a is engaged with the hook receiving means 37a in the closing position by the force in the closing direction by the torsion spring 42a, and enters the “closed state” in which the lid 7 is closed. At this time, the acute angle hook 29b is in the open position by the force of the return spring 42b and does not act on the hook receiving means 37b.

<Opening force from inside by obtuse angle lock>
The force that opens the lid 7 from the inside in the “closed state” will be described. In the “closed state”, as shown in FIG. 5A, the obtuse angle hook 29a is engaged with the hook receiving means 37a. When a force that opens from the inside of the lid body 7 is applied in this state, a force is applied in the direction of the arrow from the second support shaft 41 toward the front. The angle α2 of the hook portion connecting the second support shaft 41 from the engaging surface of the obtuse angle hook 29a with the hook receiving means 37a is an obtuse angle of, for example, about 105 °. It is the structure which produces the rotational force of the opening direction.

  That is, when a force of a predetermined level or more is applied forward and the force in the direction of opening the obtuse angle hook 29a becomes larger than the force in the closing direction of the torsion spring 42a, the obtuse angle hook 29a rotates and engages with the hook receiving means 37a. Is removed and the lid 7 is opened.

  If the angle α1 of the hook portion of the obtuse angle hook 29a is increased, the obtuse angle hook 29a is easily detached, so that it can be opened from the inside even with a smaller force. That is, the force which opens the cover body 7 from an inner side can be set suitably by selecting angle (alpha) 1 suitably. This force can be set to 70 N or less, for example.

<Lock state with acute angle hook>
Next, the “locked state” will be described. As shown in FIG. 5B, the acute angle hook 29b is in the closed position and engaged with the hook receiving means 37b.

  The angle α1 of the hook portion connecting the second support shaft 41 from the engaging surface of the acute angle hook 29b with the hook receiving means 37b is an acute angle of about 88 °, for example. Therefore, even if a force that opens from the inside of the lid body 7 is applied forward, the acute angle hook 29b generates a force in the closing direction with respect to the hook receiving means 37b, so that the lid body 7 is securely closed without coming off. "Locked state" is maintained. In other words, the lid 7 is reliably kept closed against the force that the lid 7 receives from the inside due to clothes 6 or high-pressure hot air during operation in the washing process or drying process. In this configuration, leakage and leakage of warm air can be prevented, and the lid 7 can be prevented from opening unexpectedly during operation.

  The force opening from the inside can be set to 300 N or more, for example.

<The magnitude of the closing force by two hooks>
That is, in this embodiment, two locking hooks 29a and 29b are provided, and the lid body 7 is pushed from the inside until the obtuse angle hook 29a is released in a state where the lid body 7 is closed and the obtuse angle hook 29a is applied. The force that pushes the lid 7 from the inside until the acute angle hook 29b is released in a state where the lid 7 is closed and the acute angle hook 29b is applied is larger than the force.

<Locking hook control means>
Next, a locking hook control for performing a “locking operation” for shifting from the “closed state” to the “locked state” with the lid 7 closed and a “unlocking operation” for shifting from the “locked state” to the “closed state”. An example of the configuration of the means 38 will be described with reference to FIGS. Except for FIGS. 16 and 17, the upper case 44 is omitted and only the lower case 45 is shown for easy understanding of the internal configuration.

It is. FIG. 17 is a cross-sectional view illustrating the opening / closing operation of the obtuse angle hook 29a and the acute angle hook 29b.

<Overall configuration of slider>
13 to 17, an obtuse angle hook slider 47, an acute angle hook slider 46 provided on the lower side of the obtuse angle hook slider 47, and a set pen lever 49 provided between the obtuse angle hook slider 47 and the acute angle hook slider 46 are shown. The lower case 45 is supported so as to be movable in the left-right direction.

<Obtuse hook slider>

The other end of the second urging member 73 is urged by a second spring receiving portion 74 provided in the lower case 45.

<Control electrode>
An electrode plate (A) 75, an electrode plate (B) 76, and an electrode plate (C) 77 are provided in order from the side close to the slider 59 on the left side of the swing plate 64 or the slider 59. By detecting ON and OFF due to short-circuiting and insulation between the plates, a control signal of the locking hook control means 38 is transmitted.

  An electrode (A) 78 that protrudes to the left is provided near the upper end of the electrode plate (A) 75, and an electrode protrusion 84 that protrudes in the direction close to the slider 59 is provided below the electrode (A) 78. The electrode protrusion 84 is configured such that the slider 59 contacts the contact cam portion 63 in a predetermined range near the upper end.

  The electrode plate (B) 76 is bifurcated near the upper end, and the electrode (B) 79 is provided on the right side plate close to the slider 59 at a position facing the electrode (A) 78, and the electrode protrusion 84.

A urging force to the right is applied to the seppen lever 49 via the electrode tip 82 due to the spring property of the left side plate of the electrode plate (B) 76. When the acute angle hook 29b is in the open position and the set pen lever 49 moves to the right, the electrode (C) 80 and the electrode (D) 81 are separated from each other, and the acute angle hook 29b is in the closed position and the set pen lever 49 When the electrode moves to the left, the electrode tip 82 bends to the left so that the electrode (C) 80 and the electrode (D) 81 are in contact with each other so that the electrode plate (B) 76 and the electrode plate (C) 77 It is the structure which short-circuits.

<Drive means>
The drive means 83 is provided with a pinion gear 87 on a motor shaft 86 that is an output shaft of a motor 85 that is a drive source, and transmits output torque of the motor 85 to the outside. The first gear 88 having more teeth than the pinion gear 87 meshes with the pinion gear 87 and rotates around the idler shaft 89 while decelerating, and the second gear 90 having fewer teeth than the first gear 88 is the first gear 88. The gear 88 rotates as a unit. The third gear 91 having more teeth than the second gear 90 meshes with the second gear 90 and rotates while decelerating around the drive shaft 92, and is provided with an eccentricity by a distance r from the drive shaft 92. The pin 93 is rotated around the drive shaft 92. In the present embodiment, the drive pin 93 rotates clockwise in the figure. Since the drive pin 93 rotates while being fitted to the lower side 68 of the L-shaped groove 69 provided in the swing plate 64, when the motor 85 is driven to rotate, the drive pin 93 rotates while decelerating, via the L-shaped groove 69. Thus, the rocking plate 64 and the slider 59 are moved up and down by a distance 2r, and the cam pin 61 is moved along the case crank groove 62. The movement of the cam pin 61 along the case crank groove 62 is converted into a horizontal movement of the acute angle hook slider 46 via the crank groove 56 to open and close the acute angle hook 29b.

<Acute angle hook slider summary>
That is, by the operation of the drive pin 93 driven by the motor 85, the acute angle hook slider 46 is moved in the left-right direction via the slider 59, the swing plate 64, the case crank groove 62, and the crank groove 56 that move in the substantially vertical direction. Thus, the acute angle hook 29b is opened and closed.

<Summary of obtuse hook slider>
On the other hand, the obtuse angle hook slider 47 is not configured to operate via the motor 85 or the drive pin 93. When the lid body 7 is opened, the obtuse angle hook slider 47 moves rightward by the first urging member 52 and closes the lid body 7. In this case, the hook portion near the tip of the obtuse angle hook 29a is inserted into the first recess 50 of the obtuse angle hook slider 47, and the obtuse angle hook 29a moves to the left by the force in the closing direction of the torsion spring 42a. In this configuration, the closing operation of the operation handle 30 is performed, and the obtuse angle hook 29a is opened by the opening operation of the operation handle 30.

  In the present embodiment, a first locking hook (obtuse angle hook) 29a that can be opened and closed by operating the operation handle 30 and a second opening that can be opened and closed by a driving means including a motor 85 provided in the locking hook control means 38. Locking hooks (acute angle hooks) 29b.

  Next, a preferred shape of the crank groove 56 provided in the case crank groove 62 and the acute angle hook slider 46 will be described with reference to FIG.

  As described above, the slider 59 is moved in the vertical direction by the distance 2r, the operation is changed to the horizontal movement of the acute angle hook slider 46, and the acute angle hook slider 46 is moved by the distance (e1 + e2). is there. The angle of the bent portion of the case crank groove 62 is φ1, and the angle of the bent portion of the crank groove 56 is φ2.

  Here, for example, if e1 = 0 of the case crank groove 62 is set as a linear groove in the vertical direction, and the direction is changed only by the crank groove 56, the angle φ2 ′ of the bent portion of the crank groove 56 is approximately φ2 ′ = (φ1 + φ2 ) If it is not increased to the extent, the moving amount of the acute angle hook slider 46 is insufficient. Then, since the contact angle between the cam pin 61 and the crank groove 56 becomes as large as φ2 ′, the friction load increases, the load for moving the acute angle hook slider 46 increases, or the friction load wins and cannot operate. There is a fear.

  Therefore, the angle φ1 of the bent portion of the case crank groove 62 is substantially equal to the angle φ2 of the bent portion of the crank groove 56, and the contact angles φ1 to φ2 with the cam pin 61 are set to be substantially equal to each other. Since the increase in friction load can be prevented by preventing the increase, the lock operation and the unlock operation are stable, and a highly reliable washing and drying machine can be provided.

<Locking hook control means operation>
18 to 21 are front views for explaining the operation of the locking hook control means 38, FIG. 18 is a “closed state” in which only the obtuse angle hook is locked with the lid closed, and FIG. 19 is an acute angle hook 29b. 20 is moved from the open position to the closed position, and the “locking operation” is in the middle of the operation from the “closed state” to the “locked state”. FIG. FIG. 21 shows a “lock release operation” being released from the “lock state” in which the acute angle hook 29b is locked.

<Closed state> FIG.
In the “closed state” of FIG. 18, the drive pin 93 is at the lower end in the drawing and contacts the lower side 68 of the L-shaped groove 69 provided in the swing plate 64 so that the swing plate 64 and the slider 59 are located at the lowest position. doing. The cam pin 61 is located at the lowermost position of the case crank groove 62 and the crank groove 56, the acute angle hook slider 46 is moved to the rightmost side, and the acute angle hook 29b is moved rightward and is in the open position.

  In the “closed state”, if the operation handle 30 is operated, the obtuse angle hook 29a can be opened, the lid body 7 can be opened, and the garment 6 can be put in or taken out.

  As described above, in this state, when the lid body 7 is pushed from the inside with a predetermined force or more, the obtuse angle lock 29a is released and the lid body 7 can be opened.

<During locking operation> FIG.
FIG. 19 shows a “locking operation” in which the motor 85 is driven from the “closed state”, and shows a state in which the drive pin 93 is rotated 90 ° clockwise from the lower end. The drive pin 93 moves to the left along the lower side 68 of the L-shaped groove 69, and the swing plate 64 moves upward by the drive pin 93, and the cam pin 61 moves upward and to the left along the case crank groove 62. Then, the acute angle hook slider 46 is moved to the left to move the acute angle hook 29b in the closing direction. When the acute angle hook slider 46 is moved to the left, the set pen lever 49 is moved to the left via the acute angle hook 29b, and the electrode tip 82 is moved to the left via the set pen groove 58, so that the electrode (C) 80 is close to the electrode (D) 81.

<Locked state> FIG.
FIG. 20 shows a “locked state” where the drive pin 93 is rotated 180 ° clockwise from the lower end and is at the upper end. The swing plate 64 is moved to the upper end by a drive pin 93 moved along the lower side 68 of the L-shaped groove 69 and is further biased upward by a second biasing member 73 which is a compression spring. The slider 59 is also moved to the upper end by the drive pin 93, and the flange portion 94 provided at a part of the slider 59 comes close to or abuts against the flange receiving protrusion 53 of the obtuse angle hook slider 47, and the obtuse angle hook slider 47 moves to the right. By obstructing the movement and hooking the obtuse angle hook slider 47, the obtuse angle hook 29a is held so as not to open.

  The cam pin 61 moves all the way to the left along the case crank groove 62, moves the acute angle hook slider 46 to the left and moves the acute angle hook 29b to the closed position. The pen pen lever 49 is also moved to the left through the acute angle hook 29b, the electrode tip 82 is moved to the left, the electrode (C) 80 and the electrode (D) 81 are electrically connected, and the electrode plate (B) 76 The electrode plate (C) 77 is short-circuited. Further, the contact cam portion 63 of the slider 59 comes into contact with the electrode protrusion 84 and moves the electrode (A) 78 to the left and comes into contact with the electrode (B) 79 to contact the electrode (A) 78 and the electrode (B) 79. Are conducted, and the electrode plate (A) 75 and the electrode plate (B) 76 are short-circuited.

  In the “locked state”, the obtuse angle hook 29a is hooked and held with the hook receiving means 37a engaged, and the acute angle hook 29b is engaged with the hook receiving means 37b to close the lid 7. Since the lid body 7 is not opened from the inside, the lid body 7 does not open or leak due to the internal pressure received by the lid body 7 from the clothes 6 or warm air in the washing process and the drying process.

<During unlocking operation> FIG.
FIG. 21 shows a “lock release operation” for shifting from the “locked state” to the “closed state”, and shows a state in which the drive pin 93 is rotated 270 ° clockwise from the lower end and is at the right end. The swing plate 64 is lowered by the drive pin 93, the cam pin 61 moves to the right along the case crank groove 62, moves the acute hook slider 46 to the right, and moves the acute hook 29b in the opening direction. When the acute angle hook slider 46 moves to the right, the setpen lever 49 moves to the right through the acute angle hook 29b due to the reaction force rightward from the electrode tip portion 82. Further, the slider 59 is lowered, the contact cam portion 63 is separated from the electrode protrusion 84, and the electrode (A) 78 moves to the right. When the driving pin 93 further rotates in the clockwise direction, the state returns to the “closed state” shown in FIG. 18, the electrode (A) 78 and the electrode (B) 79 are separated from each other, and the electrode plate (A) 75 and the electrode plate ( B) Insulate from 76. Further, the electrode (C) 80 and the electrode (D) 81 are separated from each other, and the electrode plate (B) 76 and the electrode plate (C) 77 are insulated.

  The locking hook control means 38 in this embodiment changes from the “closed state” to the “locked state” through the “locking operation”, and performs a washing or drying process. After the washing or drying process, a series of operations for returning from the “locked state” to the “closed state” through the “unlocking operation” can be performed.

<Configuration with obtuse hook only>
In the “locked state”, even if there is no acute angle hook 29b and only the obtuse angle hook 29a is held in the locked state with the hook hooked, the acute angle hook slider 46 is hooked so as not to move to the right. Therefore, even if an opening force is applied from the inside of the lid body 7, it does not easily open. However, since the tip of the hook has an obtuse angle, a force in the direction of opening the obtuse angle hook 29a is generated by the force that opens from the inside of the lid body 7. Therefore, when the limit force that can hold the locked state is exceeded, the obtuse angle hook 29a, the obtuse angle hook slider 47, or the resin components such as the cases 44 and 45 are deformed, and the obtuse angle hook 29a is loosened. Alternatively, the hook receiving means 37a and 37b may come off.

  That is, by enlarging the rotary drum 11 with an increase in the capacity of the washing and drying machine, if a larger amount of clothes 6 can be washed, for example, when washing blankets or futons, in the washing process and the drying process An opening force stronger than before may be applied to the lid body 7 from the inside. In addition, even when the lid body 7 is further enlarged to improve the ease of taking out the garment 6, a stronger opening force is applied to the lid body 7 from the inside according to the expansion of the area. The configuration with only the hook 29a has a limit in maintaining the locked state.

  Alternatively, when washing or rinsing process in which the water level is higher than the boundary between the lid body 7 and the bellows 31 such as so-called high water level washing or rinsing is performed by supplying more washing water than before when washing. Since a stronger water seal is required, there is a limit in preventing the water leakage by maintaining the locked state with the configuration of only the obtuse angle hook 29a.

  Alternatively, when a high-pressure fan is used as the blowing means to shorten the drying time by high-speed and high-pressure hot air, or to improve the drying finish, the loosening between the lid 7 and the bellows 31 is prevented. There is a limit to improving airtightness.

  In the present embodiment, since the acute angle hook 29b is locked to the hook receiving means 37b in the “locked state”, even if an opening force is applied to the lid body 7 from the inside, no force in the direction of opening the acute angle hook 29b is generated. The lid 7 is securely locked, and a highly reliable washing and drying machine can be provided.

<Two hooks>
In the “closed state”, since only the obtuse angle hook 29a shown in FIG. 5A is locked, when the second support shaft 41 is pushed forward by pushing the lid body 7 from the inside, the hook receiving means 37a Since the obtuse angle hook 29a generates a moment in the opening direction, the obtuse angle hook 29a is rotated counterclockwise in the figure by a predetermined force to be detached from the hook receiving means 37a, and the lid body 7 is opened.

  Here, as the obtuse angle α1 of the hook portion angle of the obtuse angle hook 29a is smaller and closer to a right angle, the force required to open the lid body 7 increases, and as the obtuse angle α1 increases, the moment in the opening direction increases. The predetermined force required to open the door becomes small, and the lid 7 can be easily opened. The obtuse angle α1 can be appropriately selected so that the lid 7 is opened by pressing it with a predetermined force from the inside.

  In the “locked state”, the acute angle hook 29b shown in FIG. 5B is engaged in addition to the obtuse angle hook 29a. Since the hook portion angle is the acute angle α2, even when the second support shaft 41 is pushed forward, the acute angle hook 29b does not generate a moment in the opening direction. Therefore, the lid 7 can be opened during operation by the internal pressure received by the lid 7, and the watertightness caused by the bellows 31 and the door glass 32 can be reduced, thereby preventing water leakage and providing a highly reliable drum-type washing and drying machine. .

<Forced release operation>
Next, with reference to FIGS. 22 and 23, a “forced release operation” that allows the lid 7 to be forcibly opened from the “locked state” where the lid 7 is locked will be described.

  For example, when the washing and drying machine stops due to a power failure during the washing process or the drying process, the locking hook control means 38 remains in the “locked state” and the clothes 6 cannot be taken out.

  FIG. 22 shows a state in which the forcible release string 48 is pulled downward in the “locked state”. Since the forcible release string 48 is fastened to the string projection 70 of the swing plate 64 via the string guide 71, when the forcible release string 48 is pulled downward, the swing plate 64 rotates in the clockwise direction as shown in the drawing. The pin 93 moves to the bent portion 95 along the lower side 68 of the L-shaped groove 69.

  FIG. 23 shows a state where the forcible release string 48 is further pulled downward. The swing plate 64 is pulled down by the forcible release cord 48 and the drive pin 93 moves to the vicinity of the upper end of the L-shaped groove 69. The cam pin 61 is also lowered, the acute angle hook slider 46 is moved to the right, and the acute angle hook 29b is moved to the open position. As a result, only the obtuse angle hook 29a is closed.

  Since the acute angle hook 29b is in the open position and the obtuse angle hook 29a is in the closed position, it becomes the same state as the “closed state” shown in FIG. 18, and if the operating handle 30 is operated in this state, the obtuse angle hook 29a is opened from the closed position. The lid 7 can be opened.

  That is, when the washing / drying machine is stopped in the “locked state”, the forcible release string 48 is pulled downward and the operation handle 30 is operated in that state, thereby opening the lid 7 and the clothes 6. Can be taken out.

<Alarm>
Next, the case where the locking hook control means 38 detects an abnormality and sends an alarm will be described with reference to FIGS. 24, 25, and 26. FIG.

  FIG. 24 shows a case where the washing / drying machine is operated with the lid 7 opened, FIG. 25 shows a case where the obtuse angle hook 29a is broken, and FIG. 26 shows a case where the acute angle hook 29b is broken.

  In FIG. 24, since the lid body 7 is in an open state, the acute angle hook 29 b is not in the acute angle hook slider 46, and the obtuse angle hook 29 a is not in the obtuse angle hook slider 47. Therefore, the obtuse angle hook slider 47 is at a position closest to the right side in the figure by the reaction force of the first urging member 52.

  When the user presses the start switch of the washing process or the drying process with the lid 7 opened, the motor 85 rotates to shift to the “lock state” and the drive pin 93 rotates clockwise. Then, the swing plate 64 and the slider 59 are moved upward. Then, the upper end of the slider 59 comes into contact with the lower surface of the hook receiving projection 53 provided at the right end of the obtuse angle hook slider 47, thereby inhibiting the swing plate 64 and the slider 59 from moving further upward. Then, since the contact cam portion 63 provided on the slider 59 does not contact the electrode protrusion 84 and the electrode (A) 78 and the electrode (B) 79 do not contact each other, the electrode plate (A) 75 and the electrode plate (B ) Keep the OFF state while being separated from 76. As shown in FIG. 20, in the “locked state”, the electrode plate (A) 75 and the electrode plate (B) 76 are short-circuited. Therefore, it is determined that a normal “lock operation” has not been performed, and an alarm is generated.

  Accordingly, even if the user presses the start switch of the washing process or the drying process with the lid 7 opened, an alarm is generated. Therefore, the washing process and the drying process are not operated with the lid 7 open, and the operation is reliable. Can provide a highly reliable washing machine.

  FIG. 25 shows an operation when the hook portion of the obtuse angle hook 29a is broken. Although the obtuse angle hook 29a is in the closed position, the tip end hook portion indicated by the broken line is broken. Therefore, the obtuse angle hook slider 47 does not move to the left as in the “closed state” shown in FIG. 47 is in a position close to the right by the reaction force of the first urging member 52.

  Therefore, as described with reference to FIG. 24, the slider 59 abuts on the lower surface of the hook receiving projection 53 and does not move to the upper end, and the electrode plate (A) 75 and the electrode plate (B) 76 remain separated. Since the OFF state is maintained without being short-circuited even after a predetermined time has elapsed, it is determined that a normal “lock operation” has not been performed, and an alarm is generated.

  Accordingly, even if the user presses the start switch of the washing process or drying process when the hook part of the obtuse angle hook 29a is broken, an alarm is generated. Therefore, the washing process and the drying process are operated with the hook part of the obtuse angle hook 29a broken. Therefore, it is possible to provide a washing machine that operates reliably and has high reliability.
